Comment 2 Dr. David Alan Gilbert 2018-04-18 15:23:30 UTC

Hi,
  You say the reproducability is low - how low?  Can you reproduce it if you just
sit that avocado test in a loop?
Can you attach the full avocado log section for the test?

In my testing, about 1/10.
Yes, i can reproduce it with avocado test in a loop.


Now, i basically sure this is not a regression issue.
It should be a same issue with bz 1520729

> Can you attach the full avocado log section for the test?

Full avocado log was added in the attachment, and also trace log that mentioned in 1520729 comment 18:

# stap -e 'probe qemu.kvm.simpletrace.qxl* {} probe qemu.kvm.simpletrace.qemu_spice* {} probe qemu.kvm.simpletrace.display* {}' -x $pidof_qemu-kvm >/tmp/trace_$pidof_qemu_kvm
# /usr/share/qemu-kvm/simpletrace.py --no-header /usr/share/qemu-kvm/trace-events-all /tmp/trace_$pidof_qemu_kvm

Comment 5 Yanan Fu 2018-04-25 13:04:22 UTC

Created attachment 1426624 [details]
trace log for qxl* and qemu_spice* and display*

Comment 6 Dr. David Alan Gilbert 2018-04-25 13:11:37 UTC

Yeh I agree it looks like 1520729;
Gerd: Dupe?

Likely.  And we have a trace log (comment 5) now, cool.

Hi Gerd,
Repeat the same case for 80 times with the given QEMU build, all pass.
So i think this build work ~
